The deep passage seemed to be bottomless, and the three of them looked at each other, but no one offered to exit.

Nalan Yu walked in the front very cautiously, and Shi Bao and Lan Xin also cheered up and walked in bravely.

The three of them walked for a while, and Shi Bao found that there seemed to be murals of mecha painted on the dark walls, which looked mighty.

She came to her senses all of a sudden, holding a torch and looking at it with relish, and Lan Xin also saw that there was no danger around, and also looked at the mecha mural on the wall casually.

The roof of the cave is dripping with water, probably because this mountain has been surrounded by clouds and mist all day, and the natural air humidity is relatively high.

Although the water has damaged the appearance of some of the murals, it is barely clear, and the paintings on them are probably hundreds of years ago about the history of mechas.

The mecha originated in the north of the Celestial Dragon Empire, and was mainly built for a nobleman by a blacksmith in the north who usually struck iron.

The nobleman failed to get the approval of the contract beast, so he had to buy back the mecha at a high price, although he still failed in the family martial arts competition.

But her steel armor was an eye-opener when one of the elders of the family saw an opportunity and offered it to the emperor.

In order to arm those mid-level military forces with average qualifications, the emperor ordered the blacksmith to make thousands of mechs.

Unexpectedly, the newborn mecha warriors actually played a huge role on the battlefield, and as soon as they came on the field, they were a surprise soldier to crack the mammoth army of the Sun Country.

The mammoth is a large elephant with average qualifications and size, trained by the Sun Nation to be a soldier mount, and has become the Sun Nation's ace army.

Since then, the mecha legion of the Celestial Dragon Empire has also stepped onto the stage of history.

It's a pity that with the development of the times, the strength of the human race has been greatly enhanced, but the upgrading of mecha technology is too slow, and it gradually no longer has the original deterrent power.

On the contrary, the high-level primordial beast, as the contract beast of the human race, greatly improved the strength of the human race after armoring.

And the legion composed of high-level primordial beasts has also become the pillar of the empire. The Golden Lion Legion on land, the Blue Dragon Legion in the sky, and the Xuanwu Legion in the sea......

There is even a high-ranking commander who declared: "The armor of the Yuan Beast is the strongest armor, and the mecha can only be regarded as a pile of broken copper and iron at best......"

Although the mechwarriors were angry, what the senior commander said was also true.

Indeed, the cost of the mecha is much higher than that of ordinary armor, but the benefits are far inferior to the armor of the Yuan Beast, and even less useful than the leather made of the Yuan Beast's skin......

It wasn't until the mecha researchers developed large mechas, living mechas, that the mecha continued to stay on the battlefield and even be used in some advanced fields.

And the mural in the back was interrupted, which made people feel a little unsatisfied......

The three people who came here are all mecha enthusiasts, otherwise they wouldn't have come here.

All three of them were particularly interested in finding the pen notes of the legendary romance master, and even some materials for mecha research. In this way, it may be possible to research better mechs and improve the combat effectiveness of mecha warriors.

But the strange thing is that there is no life here except for the occasional sound of water drops and the strange sound of wind in the cave.

After reading a volume of murals, Lan Xin was about to see if there was anything new elsewhere, but found that the murals had begun to be painted from scratch again.

At present, they can only walk forward, walking, and find that after the end of this mural, it is the beginning of the history of the mecha just now.

At this time, Nalan Yu suddenly shouted in some surprise: "We seem to have been standing still......"

Shi Bao's words also trembled a little: "We have just been to this place. ”

Lan Xin looked at the mural she had just seen on the wall, and was also a little panicked, could it be that they had entered a new labyrinth?

The maze is the most annoying, especially in such a dark and oppressive environment.

The three of them stood there and discussed for a while, and Lan Xin proposed, "Either we will look for it again and see if there is any other way out." ”

Keep going, but this time they slowed down. Nalan Yu was still holding a torch on the wall, and some corners were carefully observed to see if there were any clues.

After walking for a long time, there are still familiar roads, familiar murals, and even the places where water drops fall.

At this moment, the three of them were a little irritable, Lan Xin looked at the mural in front of him, and felt inexplicably puzzled.

She also felt that the three of them had been trapped in place by some kind of formation, but she had obviously just heard a gust of wind.

Usually there is another exit where there is a rumor, but she is a little unsure.

In order to prove his idea, Lan Xin also said to the other two: "I seem to have heard the wind just now, and it seems that there is another way out." ”

Shi Baozheng was upset, she didn't have much patience, she heard Lan Xin say this, and hurriedly responded: "Then let's go quickly." ”

And Nalan Yu on the side said confidently: "I brought the compass made by my sister, you can come with me." I'm sure I'll find a way out. ”

Saying that, a green light shot out of Nalan Yu's mechanical eyes, and a phantom of a compass appeared in front of him. It seems that she was well prepared.

But Lan Xin had just run the Wind Whispering Spell, and she believed in her own exercises even more. Because she can come to this world, she actually doesn't believe in these technology products very much.

After all, the reborn female kingdom has appeared, and her concept has changed dramatically.

Compass, in this fantasy world, is not so convincing.

Shi Bao looked at Nalan Yu, then at Lan Xin, and finally said: "I believe in Blue Pipi, I'll go with Blue Pipi." ”

Nalan Yu insisted: "You have to believe me, the compass made by my sister is very useful here, and we successfully brought back a mecha here last time." ”

Lan Xin secretly complained in his heart: "Hehe, if it's useful, I've been walking the maze for a long time, and I'm seriously injured by the mecha?"

But after all, in the current tense of teammates, it is not easy for her to directly say those hurtful words in her heart.

Lan Xin was very happy that Shi Bao believed in herself, but at this time she had to say something nice: "Sister Yu, or we will split into two teams." You take the compass away, and I walk according to my feelings. As soon as which team finds a way out, a signal is immediately sent to inform the other side. ”

When Nalan Yu heard this, she had no choice but to nod and agree, she took a breath and said, "That's okay, you pay attention to safety." ”

So the three of them split into two teams and began to follow what they thought was the right path.

Nalan Yu took the compass and started it, but he was still a little uncomfortable in his heart: "Two little children, what do you know?" Hehe, wait for you to cry and come back and beg me ......."

And Lan Xin took Shi Bao and walked forward according to his feelings.

Originally, the three of them were still walking together, but slowly, because they had been observing their surroundings, it was relatively dark. No one noticed that there was no one around.

Lan Xin and Shi Bao took one way, and Nalan Yu took the compass the other way.

After I don't know how long, the three of them found that they were still familiar with the murals, the familiar water droplets, and the familiar scenes. Before they knew it, they were no longer three......

What's going on here?

Is it a hallucination?
